摘要： An image processing method according to the present invention is contrived to change the gradation level (of the color component corresponding to the complementary color of yellow) for a pixel within a zone located on a corner of a rectangular image so as to maximize the difference between the gradation level of a pixel that is a processing target and the gradation level of a pixel in a background area in the surrounding area of the pixel that is the processing target, that is, lowering the gradation level. This means the pixel that is a result of applying the process for changing the gradation levels looks yellowish. The human eye has difficulty in recognizing yellow and therefore the change applied to the pixel is inconspicuous as compared to the case of placing a mark or frame on the outside of a rectangular zone.

摘要： An image reading apparatus is attached to the top of a PDA. During the image reading operation, an operation state control signal is output from the image reading apparatus to the PDA. According to the signal, the intensity of an input display unit not required during the operation can be reduced. Additionally, the power supply or the supply of a signal not required during the operation is stopped. Furthermore, an LED of the PDA issues a notification of an operation state by lighting, blinking, or turning-off. When the input display unit displays an image, an erect image and an inverted image are appropriately switched depending on the operation state. During an image reading operation, input by input buttons and a touch panel of the input display unit are nullified to avoid the occurrence of a malfunction.

摘要： First, the original data C is divided into an n number of pieces of partial data C1-Cn. Then pieces of position information P1-Pn are added to those pieces of divided partial data, and they are respectively embedded into the n number of duplicated images. Then, the resultant images E1-En are produced. The resultant images are displayed in the same position on a display screen as a still image for T1 seconds each. In a camera of a mobile phone, etc., the displayed images are repeatedly photographed at an interval of T2 seconds that is shorter than T1 seconds, and the pieces partial data C1-Cn and position information P1-Pn are sequentially extracted. When all the processes are completed, the pieces of partial data are integrated on the basis of the pieces of position information P1-Pn. As a result, the original data is obtained.

摘要： In an image authentication system, a printing unit prepares a code in a form of an image of a different density in any two adjacent blocks, and prints the code onto a recording medium as a printed image. A storage unit stores therein image data corresponding to printed images and codes to be embedded in image data corresponding to the printed images in a correlated manner. An authenticating unit receives scanned image data corresponding to a printed image, extracts a code embedded in the scanned image data and authenticates the printed image corresponding to the scanned image data based on extracted code.

摘要： Image identifier information specific to image data to be input to an image search apparatus is embedded in the image data as a steganography in advance. Meanwhile, the side of an image search apparatus decodes the steganography contained in image data, detects the image identifier information, compares the detected image identifier information with an externally instructed search condition and outputs image data if the aforementioned two kinds of information are identical.
